History of Rockville

Early Days: Native Americans and First Settlers

Rockville is located in a hilly area called the Piedmont region. It has three creeks: Rock Creek, Cabin John Creek, and Watts Branch. These creeks made it a great place for early Native Americans to live. They were semi-nomadic, meaning they moved around. Some groups settled down into farming communities around 8000 BC. They grew plants like sunflowers.

Around 1200 AD, these groups, sometimes called Montgomery Indians, faced conflicts. Other tribes like the Senecas and Susquehannocks moved south. Over time, six ancient sites have been found in Rockville. Many old tools and items, thousands of years old, have also been discovered. By 1700, most of the original people had left due to European settlers.

Native Americans created a path on high ground, called Sinequa Trail. This trail is now where downtown Rockville is. Later, a main road, the Rock Creek Main Road, was built here. In the mid-1700s, Lawrence Owen opened a small inn called Owen's Ordinary. This inn became important when Major General Edward Braddock stopped there in 1755. He was on a mission from George Town (now Washington, D.C.). The road's high location kept it dry all year.

The 1700s: How Rockville Got Its Start

The first land claims in the Rockville area were made by Arthur Nelson between 1717 and 1735. Within 30 years, the first permanent buildings were built in what would become Rockville. At first, Rockville was part of Prince George's County. But as nearby Frederick Town grew, the western part of the county, including Rockville, became Frederick County in 1748.

Because it was a small, unincorporated town (meaning it didn't have its own official government yet), early Rockville had many names. People called it Owen's Ordinary, Hungerford's Tavern, or Daley's Tavern. The first time the settlement was written about was during the Braddock Expedition in 1755. A soldier wrote about marching to "Owings Oardianary," calling it "a Single House, it being 18 miles and very dirty." Owen's Ordinary was a small stop on Rock Creek Main Road. This road went from George Town to Frederick Town. It was one of the busiest roads in Maryland at the time.

On September 6, 1776, Maryland decided to divide Frederick County into three smaller areas. Rockville was in the southern part, which was named Montgomery County. George Town was the biggest town in this new county. But it was too far south to be the county seat (the center of local government). Rockville was small but centrally located and well-traveled. So, it was chosen as the county seat. At this time, Rockville still didn't have an official name. People often called it Hungerford's Tavern. After it became the county seat, people started calling it Montgomery Court House. The tavern served as the first courthouse on May 20, 1777.

In 1784, a local landowner named William Prather Williams hired someone to map out the town. In his honor, many started calling the town Williamsburg. But people still used Williamsburg and Montgomery Court House interchangeably. Rockville became more important when Montgomery County was created. It also grew when George Town was given to the federal government to create the District of Columbia.

The 1800s: Naming the City and Civil War Times

A plan to name the town Wattsville, after the nearby Watts Branch creek, didn't happen. People thought the creek was too small to name the town after. On July 16, 1803, the area was officially recorded as "Rockville." This name came from Rock Creek. Even so, the name Montgomery Court House still appeared on maps until the 1820s.

On March 10, 1860, Rockville officially became an incorporated village. This meant it had its own local government. During the American Civil War, General George B. McClellan stayed at the Beall Dawson house in 1862. Also, General J.E.B. Stuart and 8,000 Confederate soldiers marched through Rockville. They occupied the town on June 28, 1863, on their way to the Battle of Gettysburg. They stayed at the Prettyman house. Another general, Jubal Anderson Early, also passed through Rockville in 1864.

In 1873, the Baltimore and Ohio Railroad came to Rockville. This made it easy to travel to and from Washington, D.C.. In 1891, Rockville got its first trolley service. It connected to a railway line that went to Georgetown.

The new railroad and trolley service connected Rockville to Washington, D.C. Trolley service ran for 40 years. But by 1935, more people were using automobiles, so the trolley stopped. Bus service was available from 1924 to 1955. Rockville didn't have much public transportation again until the 1970s. That's when the Washington Metropolitan Area Transit Authority (WMATA) started extending the Washington Metro subway system.

The Rockville Metro station opened on July 25, 1984. The Twinbrook station opened on December 15, 1984. Metrobus service also expanded into Montgomery County. In 1979, Montgomery County started its own Ride On bus service. The MARC commuter train also serves Rockville. It connects to Washington Union Station in Washington D.C. and to Frederick. Amtrak, the national passenger train system, also has service from Rockville to Chicago and Washington D.C.

Rockville grew a lot in the mid-1900s. The Twinbrook area became part of the city in 1949. This added hundreds of new homes and thousands of residents. In 1954, Congressional Airport closed. Its land was used to build homes and a shopping center called Congressional Plaza, which opened in 1958. These new areas offered affordable homes for young families after World War II.

During the Cold War, people thought it was safer to stay in Rockville. This was in case of a nuclear attack on Washington, D.C. Bomb shelters were built, including a large one at Glenview Mansion. The I-270 highway was even planned as an emergency landing strip for aircraft.

From the 1960s, Rockville's town center started to decline. It used to be a main shopping area. Rockville became the first city in Maryland to try a government-funded urban renewal program. This meant tearing down most of the old business district. They built the Rockville Mall, but it didn't do well and was torn down in 1994. They also built new government buildings, like the Montgomery County Judicial Center.

Even though the plan had problems, efforts to improve the town center continued. Most of the city's business activity moved along Rockville Pike. In 2004, Rockville Mayor Larry Giammo announced plans to update the Rockville Town Square. This included new stores, homes, and moving the city's library. Today, the new Rockville Town Center has many unique stores, restaurants, and apartments. It also has stages, fountains, and the Rockville Library. The U.S. Nuclear Regulatory Commission's main office is just south of the city.

Rockville is also connected to nearby towns like Kensington and North Bethesda. The Music Center at Strathmore, an arts center, opened in 2005. It is a second home for the Baltimore Symphony Orchestra. The Fitzgerald Theatre in Rockville Civic Center Park has offered entertainment since 1960. In 1998, Regal Cinemas opened in the Town Center, and the city added 900 acres of land.

Rockville also has a brass band that plays in the British style. The band R.E.M. released a song in 1984 called "(Don't Go Back To) Rockville". It was written about not wanting someone to return to Rockville. In 1975, the famous writer F. Scott Fitzgerald and his wife Zelda Fitzgerald were buried at St. Mary's Catholic Church in Rockville.
